I seem to remember in the early 80's on the line on 56(F), that all the F4M's up to XV 417 had hydraulic wing fold, a switch in the L/H undercarridge bay, and a speed brace was all that was required. XV407 definitely did, as I had to make use of it at greenham common 1981 for the airshow to get the aircraft into the static line up, a little tight to say the least.
